NITEID STATES, PATENT OFFICE.-

GEORGE G. HENNING, OF WASHINGTON, DISTRICT OF COLUMBIA.

IMPROVEMENT l N HAND-RESTS.

Specification forming part of Letters Patent No. 209,761, dated November12, 1878; application filed March 13, 1878.

To all whom it may concern:

Be it known that I, GEORGE O. HENNING, of Washington, in the District ofColumbia, have invented certain new and useful Improvements inHand-Rests for Book-Keepers; and I do hereby declare that the followingis a full, clear, and exact description of the invention, which willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawin gs, and toletters of reference marked thereon, which form a part of thisspecification.

Figure 1 is a top or plan View of the handrest. Figs. 2 and 3 aresections on w w and y y of Figs. 1 and 4. Fig. ,4 is a View of the restin use in a book. Fig. 5 is a top view of another form, and Fig. 6 is asection of Fig. 5.

This invention relates to improvements in arm or hand rests for the useof book-keepers and copyists and consists in forming the cleat acrossthe top with a recess, by which the board is sustained by the cover ofthe book, and by the insertion in the cleat of a piece of indiarubber orother elastic substance, so that the rest may be sustained by the edgesof the leaves of the book as the same may-be employed, all of which willbe hereinafter more fully described.

In the drawings, A represents a board made of suitable material, and ofa width to accommodate the leaf of the book in which entries are to bemade or copied. The length of the board A must be so much longer thanthe book as to afford below the page a hand-rest, which is shown at A. Bis the ledge, projection, or cleat, securely fastened to the board A.

Figs. 1, 2, and 3 show the manner of constructing the cleat B, by makinga hollow or cavetto in the edge, as at b. I also insert in the edge of Ba thin strip of india-rubber, as at a, Fig. 2, and by a broader strip inthe edge, as at a, Fig. 3. These are used to impinge upon the edges ofthe leaves of the book, and by friction to sustain the arm-rest abovethe book while the hand bears upon the lower part.

In ordinary hand-rests inserted from below there is no support for therest in the commencement or close of the book. In this invention theboard is sustained by the back of the book in the commencement and closeas well as in any other part.

The present book-rests may have this improved cleat by simply forming arecess, 1), as seen in Fig. 2, and applying the rubber strip.

When the hand-rest is to be used below, the board can be turned over andrun on the bookback 0, and the edge of the book inserted in recess 11.The rest will then be properly supported.

I claim- The arm-rest having the stock B, with a recess, b, andindia-rubber strip or block a, substantially as and for the purposedescribed.

In testimony that I claim the foregoing as my own I hereto affix mysignature in presence of two witnesses.

GEORGE O. HENNING.
